first, you have to know what kind of beacon you have: Proximity beacon, Location beacon or Sticker beacon? You can watch for the Estimote web-site. To be sure, note that the Sticker beacon is the small one, the Proximity beacon is the "basic" one and the Location beacon the stronger one. It will inform you with the data you can have from your beacon:
- if you have a Proximity beacon, you can catch the Eddystone-TLM packets sent,
- with a Location beacon, you can both recover the Eddystone-TLM and Estimote Telemetry packets that your beacon broadcasts,
- the Sticker beacons have their own Nearable with Telemetry packet.
To build an Android app' using the Estimote technology, you have to follow the instructions given in the Estimote Android SDK GitHub page:
You have some templates in the GitHub (here), but it's more convenient to follow the on-line guide. Follow the changelog file if you're blocked with old classes/methods.
I can't help you with the claim issue, need here an Estimote staff member.
